HUBERT WITTE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO ST. LOUIS OAR COMPANY, OF ST. LOUIS, MISSOURI.

WINDOW-SHADE-RETAINING DEVICE.

SPECIFICATION forming part of Letters Patent No. 758,344, dated April 26, 1904.-. I

Application led September 14, 1903. Serial No. 173,080. (No model.)

To all whom it may concern,.-

Be it known that I, HUBERT WITTE, a citizen of the United States, residing in the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Window-Shade-Retaining Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part 'of this specification.

My invention relates to a retaining device for holding car-window shades in anyT position into which they may be moved.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a front elevation of a shade applied to a window and-containing my retaining device. Fig. II is a vertical section o i my retaining device with parts broken out. Fig. III is an end view of the curtain-retaining device. Fig. IV isapartial section taken on line IV IV, Fig. II. Fig. V is a view'illustrating a modification of the means for operating the retaining-device rods.

A designates the frame of a window in which re the usual grooves B. (See Figs. II and Gis a Window-shade in which my improved device is shown.

1 designates a sleeve seated in the lower end i return the shoes to the window-frames to of the window-shade and extended transversely through a pocket therein. In this sleeve is a longitudinal slot 2.

3 is a face-plate secured to the sleeve I at the location ot' the slot 2 by a screw li. The face-plate 8 contains slots 5, that register with the slot 2 in the sleeve l.

6 designates a pair of pull -fingers that are arranged to operate in the sleeve l and which project through the slots 2 and 5 to permit of theirA being grasped by a persons lingers to move them toward each other.

- 7 designates pull-'rods each having its inner end seated in the pull-fingers 6 within the sleeve l and extending through said sleeve and beyond its terminations. Seated in each end of the sleeve l are-two armed bearing-bars 8. These bearing-bars have bushing portions 9, which enter the sleeve and are provided at their ends with pairs ofv lips 10. The pullrods 7 extend loosely through the bushing portions 9 of the bearing-bars 8.

l1 designates leaf-springs secured intermediate of their ends to the outer ends of the pull-rods 7. VThe ends of these leaf -springs bear against the bearing bars 8 between the lips l0, as seen in Figs. II and III.

12 designates shoes carried by the pull-rods 7 and resting against the outer faces of the leaf-springs 11. f

In the practical use of my retaining device vthe leaf-springs ll exert a constant pressure against the bearing-bars 8, and they ride in the window-frame grooves B to hold the shoes 12 at their outer faces against the windowframe at the bases of the grooves therein. In this manner frictional engagement between the device and the windowlframe is secured and the shade is held at any point to which it 'may be moved. When the shade is to be raisedv or lowered, the pull-lingers 6 are drawn toward each otherto create a pull upon the pull-rods 7, and the leaf-springs 1l are thereby moved toward the bearing-bars 8, while their ends remain in bearing with said bars and the friction-shoes 12 are removed from engagement with the Window-frame, so that the shade may be moved. Immediately upon the pull-iingers being released the leaf-springs again hold the shade.

In Fig. V, I have shown a modification of the means for moving the pull-rods of my device. In this modification each pull-rod 7 L bears at its inner end a rack 7b. 6a is a pinion that meshes with the teeth of both of the pull-rod racks and which when rotated serves said sleeve, leaf-springs to bear against said bearing-bars, pull-rods for compressing said leaf-springs, and friction-shoes carried by said leaf-springs, substantially as set forth.

3. In a shade-retaining device, the combination of a sleeve, bearing-bars .fitted to the ends of said sleeve and having diverging arms, lips carried by said bearing-bar arms, pulirods operated in said sleeve, 1eaf-springs oonnected to said pull-rods and having their free IO ends seated between the lips of said bearingbars, and friction-shoes at the outer faces of said leaf-springs, substantially as set forth.

HUBERT WITTE.
